I begin to keep a diary to improve English skill from today. Frankly speaking, I have tried to do so many many times, but I couldn't continue it so far. I'm not sure about whether I can manage to keep a diary this time or not, because first year of Ph.D. in Economics is said to be very hard and tough. Just let me try.

Two weeks have passed since school began. I think I have to spend much more time to study than other economics guys because I am not familiar with many concepts of economics. Today, I bought a textbook about probability and statistics. I wonder how many book we have to buy and read to study economics.
